In the context of the Marie Curie ATLANTIC project, I could benefit from 2 days training in CUDA and OpenACC. This knowledge is today essential for harvesting the power of high power computers nowadays. Pictures of the event are available here.

It was an honor to be invited by prof. Yabana and Dr. Otobe to the Kansai Photon Institute in Japan for having an excellent workshop there and visiting Kyoto and Nara, the former capital cities of Japan.
Title of the seminar was “Predicting laser surface nanostructuringusing dispersion laws in the complex plane.”

On June 19th, TJY Derrien was honored to present a seminar in the group of Prof. Ishikawa (University of Tokyo).
Title was: “Predictive modeling of materials excitation, melting and nanostructuring upon femtosecond laser irradiation: first-principle and phenomenological perspectives”.
Duration of the talk was 1h. Here is the link to the official announcement.

The project IT4I/MORILLE has been granted. It consists in providing a computational time of 3.5 M core-hours to implement the Marie Curie ATLANTIC project we obtained with HiLASE and with a number of partners. The PI is Dr T. J.-Y. Derrien, and the project includes the training of several people at HiLASE, plus the hosting of the incoming researchers of the ATLANTIC project.

Thanks to this project, HiLASE has now access to all the scales of machines that are necessary to prepare efficient HPC simulation codes.

Our paper titled “LIPSS on thin metallic films: New insights from multiplicity of laser-excited electromagnetic modes and efficiency of metal oxidation” has been published in Applied Surface Science (IF 4.4).

The paper explains the period of Laser-Induced Periodic Surface Structures (LIPSS) on thin Cr film, with accounting for the influence of the substrate. It also provides a convincing model of HSFL formation where the role of metal oxidation is dominant.
